Understanding your bill

Customer Charge (or Basic Charge) – Single Phase & Three Phase, Single-Family Home Single Phase & Three Phase and Multifamily Home Single Phase & Three Phase
This fixed monthly charge covers some of the costs associated with having electric service regardless of the amount of electricity used (i.e. cost of meters, meter reading, billing, record-keeping, etc.).

City Franchise Tax
This charge is collected on behalf of the city. All taxes are remitted to the city for its use.

Community Clean Energy Program (Schedule 100)
Starting in January 2027, customers in 16 participating communities can support renewable energy for an additional charge. The Community Clean Energy Program is a state-authorized program established through Utah legislation passed in 2019. Program rates and details are defined in Schedule 100. 

Customer Efficiency Services (Schedule 193)
This charge recovers the cost of energy efficiency programs. The percentage is applied to charges on customers’ applicable rate schedule. The percentage rate is applied to the applicable charge components as defined on Schedule 193 and the customers’ applicable rate schedule. 

Demand charge (kW)
Demand charge is measured in kilowatts (kW). This is a measurement of capacity or the rate at which energy is used. Demand represents the greatest amount of energy used in 15-minute intervals during a billing cycle. High demand is usually associated with equipment start-up, which requires higher energy use than routine operations. 

Electric Vehicle Infrastructure Program Cost Adjustment (Schedule 198)
This recovers costs associated with electric vehicle charging infrastructure in Utah based on Utah Code 54-4-41 to recover investment in utility-owned vehicle charging infrastructure. The percentage rate is applied to the applicable charge components as defined on Schedule 198 and the customers’ applicable rate schedule.

Energy Balancing Account (EBA) Rate (Schedule 94)
The EBA is a price adjustment (either credit or debit) that accounts for differences between actual power costs and the level of power costs that were set in customer rates. Power costs are the variable costs of providing customers with energy, including such things as fuel and the cost to purchase power from other producers. Power costs are offset by wholesale sales the Company makes to other utilities and entities that purchase wholesale power. The percentage rate is applied to the applicable charge components as defined on Schedule 94 and the customers’ applicable rate schedule.

Energy charge (kWh)
Electricity is measured in watts, like gasoline is measured in gallons. A kilowatt-hour is 1,000 watts used steadily for one hour – a measurement of the rate of electrical energy used multiplied by the length of time it is used. The average Rocky Mountain Power customer uses approximately 720 kWh per month or 8,640 kWh per year.

Energy Charge (Block 1, Block 2): This charge reflects the costs of providing and producing electricity not recovered through the basic charge. Customers are charged based on the number of kWh used. Usage of 0-400 kWh is charged at the lowest rate (Block 1), and all additional kWh usage above 400 at the higher rate (Block 2).

Home Electric Lifeline Program
This state-mandated surcharge is used to collect funds for the Low-Income Residential Lifeline Program in Utah.

Municipal Energy Sales and Use Tax
This charge is collected on behalf of the city. All taxes are remitted to the city for its use.

Power factor or reactive power (kvar)
Power factor (or reactive power), measured in kilovolt-amperes (kvar), results from equipment that draws more current from the electrical system than usual. Customers can reduce this charge by turning off unused motors and other equipment and by installing capacitors. 

Rate schedule
Identifies rate category for your service address. This determines the rate you are billed.

Renewable Energy Adjustment (Schedule 98)
Renewable Energy Certificates (REC) are used for transferring, trading, selling or buying environmental benefits associated with renewable energy. Rocky Mountain Power sells a portion of the RECs it generates yearly. Revenues from sales are credited against the cost of providing energy. The market value and the quantity of RECs sold vary year to year. The Renewable Energy Adjustment on customer statements can be either a credit or debit based on the actual REC revenues received. The percentage rate is applied to the applicable charge components as defined on Schedule 98 and the customers’ applicable rate schedule.

Time of Use rates
With optional Time of Use rates, customers pay more for energy used during peak times of the day and less for energy used during off-peak times. 

Utah Sales Tax
Rocky Mountain Power collects sales tax for the Utah State Tax Commission as required to conduct business in the state of Utah.

Basic Charge – Single Phase & Three Phase
This fixed monthly charge covers some of the set costs associated with having electric service, costs the company incurs regardless of the amount of electricity used (i.e. cost of meters, meter reading, billing, record-keeping, etc.).

Energy charge (kWh)
Electricity is measured in watts, like gasoline is measured in gallons. A kilowatt-hour (kWh) is 1,000 watts used steadily for one hour – a measurement of the rate of electrical energy used multiplied by the length of time it is used. The average Rocky Mountain Power customer uses approximately 709 kWh per month or 8,508 kWh per year. This charge covers the cost of both distribution (i.e. lines, transformers, conductors, etc.) and generation (i.e. power plants, transmission, etc.) of electricity. Customers are charged for the number of kilowatt-hours (kWh) used.
